A snowmobile drive track includes an endless body having a ground engaging outer side on which is displayed, on every three successive crossbar receiving areas, a tread pattern which is repeated over the entire outer side. This profile configuration allows for a reduction of rubber material on the track and, therefore, a reduction of noise produced by the track as it rotates.
